WINDOW-STOP.

Specification of Letters Patent.

Patented March 23, 1909.

Application filed October 31, 1907. Serial No. 400,045.

To all whom it may concern.-

Be it known that I, ROBERT FLEETWOOD NIoHOLs, a citizen of the United States, residing at Oakland, in the county of Alameda and State of California, have invented a new and useful Improvement in Window-Stops, of which the following is a specification in such full and clear terms as will enable those skilled in the art to construct and use the same.

This invention relates to a window stop bead fastener used for the purpose of securing the stop bead'adjustably and removably in the proper place in a window frame.

The object of the invention is to produce a device which will secure the stop bead easily and quickly in any desired adjustment with respect to the sash, and which will permit the easy removal of the bead when it is desired to remove the sash from the frame to wash the glass. I

In the drawing, in which the same numeral is applied to the same portion throughout, Figure 1 is a view of a window frame and sash with the removable stop and lock applied thereto, Fig. 2 is a vertical section of the window frame showing the stop bead and the locking device, Fig. 3 is a front view of the locking plate, Fig. 4 is a back view of the locking plate, Fig. 5 is a view of the lock, showing it in the osition in which it is when ready to release t e stop bead, Fig. 6 is a sectional view of the locking plate on the dotted line Fig. 3, Fig. 7 is a front view of the looking plate in its place on the frame of a window, Fig. 8 shows the lock and the stop bead in front elevation, and Fig. 9 shows the plate which holds the lock in its place.

The device is in two parts, one a plate which is permanently secured to the window frame, and the other the lock and plate which secures it ermanentl to the sto bead, the P Y F wire 10 pressed in a groove in the shankp lock being passed through a ho which is bored in the stop bead.

The window frame 1 holds the sashes 2, 2 in place, the stops 3, 4 and 5 holding the sash from falling out toward the front. The stop bead 3 is removably held in its place by means of the locks 6, 6, and in order that the end may not open where it meets the stop bead 4 it is cut on the bevel shown at 7, the top bead being firmly nailed in place.

The lock has the cylindrical shank 8 and is held in place in the plate 9 by having the 11, and the said edges are reversely beveled is to the same extent as the reverse cams, or in- .clines, 16 on the locking plate 14, the object of said bevels being to prevent the look from wearing the locking plate, as would be the case if the lock did not have the same bevel as the cam faces of the locking plate.

The locking late 14 has two screw holes to secure it to t e window frame, and in or der to permit the adjustment of the stop bead it has the slot 15 cut in it. The metal on each side of the slot in the said plate is pressed up as shown at 16 to form a pair of cam faces, or reverse inclines, as indicated on Fig. 4, the cams, or inclines, running out at the end of the dotted lines and being highest at the end of the full lines. The result of this construction is that the shank may be placed in the slot at any place and locked at any place, since the distance between the inner edges of the flat head 12 is such as to cause the lock to be tight when the flat head is turned so it will reach the two high parts of the cams 16.

It will be noted that the plate 14is circular in shape, the object being to sink the same in the window frame with as little trouble as possible, a single hole being bored to place completely fills the hole through which it passes it makes it very firm even without the outer plate, but the latter is screwed to the stop bead for the pur ose of reventing 1t from dro ping out. t will a so be noted that the handle on the lock is arranged in such a position with respect to the lockin head 12 that when the sto bead is securec in place the handle is in tie most convenient position for the fingers to unlock the same.

Having thus described my invention what I claim as'new and desire to secure by Letters Patent of the United States is as follows:

In astop bead lock, the combination of a plate adapted to be sunk in a window frame and having a slot, a pair of reverse cams struck up on said plate 011 opposite sides 01' surrounding the shank and holding it to the said slot, a shank provided With a thumbbearing plate. piece on one end and having a smaller shank In testimony whereof I have set my hand on the other end adapted to pass through the this 23d day of October A. D. 1907, in the 5 slot in said plate, said smaller shank eerlrying presence of the two subscribed witnesses. 1;]
